Trailing Commas

[tzengshinfu]

Hello folks:

I have to admit that trailing commas are quite convenient when it comes to
reordering multiple lines of parameters. However, for a single line of
parameters, visually, I always tend to feel like the last element has been
forgotten (just a personal perspective).

Similar situations exist in Javaworld:
- JSON strings (supportive)
- SQL syntax (unsupported)

Perhaps, should this functionality be placed within the IDE rather than the
compiler? Using shortcuts to rearrange multiple lines of parameters, could
the IDE automatically add or remove commas at the end?

(However, if this is the case, this suggestion might veer away from the
main topic of our mailing list.)😅
